SEWING-MACHINE FINGER-GUARD.

Specification of Letters Patent.

Patented July 20, 1915.

,Application filed June 14, 1910. Serial No. 566,725.

To all whom it may concern:

Be it known that I, MARCUS MASHBIR, a citizen of the United States, anda resident of New York, borough of Brooklyn, county of Kings, and Stateof New York, have in: vented certain new and useful Improvements inSewing-Machine Finger-Guards, of which the following is a full, clear,and exact specification.

This invention relates more particularly to a guard adapted to co-actwith the resser-foot of a sewing machine to prevent injury to thefingers of the person by the needle of the machine when in operation.

The object of the invention is to provide a finger guard or device foruse in conjunction with different constructions of sewing machineswherein one or more needles may be employed and which is adapted to beoperatively connected or formed integral with the presser-foot forefliciently preventing the finger of the operatorfrom contacting withthe needle or needles of the machine and more particularly when thecharacter of the stitching requires the material being sewed to beguided in various directions in which instances frequent injuries occurby reason of the fingers accidentally slipping under the needle, and afurther, object of the invention is to provide a form of device whichwill permit the quality of the stitching and straightness of the seam tobe carefully observed as the work progresses.

Furthermore, my invention consists of certain other novel features andparts as hereinafter described and pointed out in the claim at the endof the description and illustrated in the accompanying drawings forminga part of this specification, in which Figure 1 is a perspective view ofone form of the guard embodying my invention. Fig. 2 is a side view ofthe guard detachably held to the arms of the presser-foot. Fig. 3 is afront elevation of the guard detachably held to the arms of thepresser-foot. Fig. 4 is a view of a different arrangement of the guard.Fig. 5 is a view of a form of the guard adapted to be used with a sewingmachine wherein two needles are employed.

The presser-foot bar 10 is adapted to be movably held in the head of asewing machine, as at 11, and to said Presser-foot bar is detachablyheld the p'resser-foot 12 by the screw 13 passing through the recessedboss 14: formed at one end of the presserfoot 11 and engaging the bar10, all of which may be of the usual or any preferred construction.

In the machine head 11 is movably held in the usual manner the needlebar 15 carrying the needle 16, and when one needle is used in a sewingmachine the presser-foot 12 is provided with a slot, as at 17, andcommunicating opening through which the needle passes in itsreciprocatory movement when the machine is in operation. By slotting thepresser-foot lengthwise thereof, as indicated, the spaced arms 18 and 19are thereby formed, and vertically disposed at the ends of said arms isarranged a fingerguard or device 20. In Fig. 1 the guard 20, consistingmainly of the body 21 and the curved, or semi-circular transverse legs22 and 23, is formed integral with the presserfoot 12. Between the legs22 and 23 the peep-opening 2st is provided and through which thecharacter of the stitching and straightness of the seams of the materialmay be carefully observed by the operator of the machine. This form ofguard is provided by the spaced elongated arms or toes 18 and 19 of saidresser-foot and angularly bonding said arms or toes substantiallycentrally of the length thereof so that the guard will be disposedupwardly in front of the needle 16, and by this arrangement an opentransverse space 25 is provided above the upper surface of thepresser-foot 12 between the body 21 and presser-foot bar 10 for the freemovement of the needle 16.

In Figs. 2 and 3 the presser-foot 26 is of the usual form employed insewing ma chines and has one toe 28 which is longer than the toe 27 andto said, presser-foot is detachably and adjustably held another form offinger guard 29. The body 30 of this guard 29 is similar in form to thebody 21 of the guard 20 and has two parallel arranged legs, as 31 and32, between which is provided the peep-opening 33. The body 30 isvertically disposed preferably upon and adjacent to the free end of thetoe 28 for providing an open transverse space 34 between said body andthe presser-f0ot bar 10. At the lower end of the leg 31 of the body 30is formed aboss 35 having an opening 36 for the reception of'the freeend of the arm 28 so that the body may be adjusted along said toe, andwhen adjusted in position said body is rigidly held to the presserfoot26 by a screw, as at 37. To reinforce this means of connecting the body30 to said presser-foot a bracket 38 is arranged to extend from the boss35, and said bracket may be of a shape adapted to rest snugly uponv theupper surface of the toe 28 of the resser-foot. A slot 39 is formed inthe bracket 88 and passing through said slot and held in thepresser-foot is a screw 40 lfiy which the guard. may be clamped to thecot.

In Fig. 4 is illustrated a presser-foot 41 and aguard 42 formed separatetherefrom. Projecting upwardly from said guard is a rod 43 the free endof which, as at 44, is adapted to be movably held in a recess formed inthe machine head 45. A spring 46 encircling the rod 43 is interposed between the guard 42 and machine head 45 and normally serves to force theguard and said rod downwardly.

A finger guard 47 is shown in Fig. 5 which is adapted to be used inconjunction with a sewing machine wherein may be employed two or moreneedles for producing a plurality of rows of stitching. In constructionthe presser-foot 48 is provided with a longitudinally projectingpresserplate 49 having openings, as at 50, through which the needles 51,held to the needle bar 52 pass when the machine is operated. At one endof the presser-plate 49 is provided a recessed boss 53 adapted to fitupon the end of the presser-foot bar 10 and is rigidly held thereto by ascrew, as at 54, passing through an opening in said boss and held in thepresser-foot bar. lhe opposite end of the longitudinal presser-plate 49is slotted for a part of its length so as to provide a peep-opening 55between two legs 56 and 57 of a body 58 of the guard. At the lowerextremity of the arms 56 and 57 the presserplate is angularly bent so asto position the body 58 vertically upward transversely in front of theneedles. Where a plurality of needles are employed in a sewing machine,it is clear, that this form of guard will be of greater width than theguard used with a machine employing only one needle, and thepeep-opening 55 will be correspondingly wider. To prevent the fingers ofthe operator from accidentally passing through said peep-opening a plateof glass, as at 59, 'or other transparent material is held in the guardto close said peep-opening at the same time permitting the work of thestitching to be seen therethrough, and-by thus positioning the guard 47a transverse space is provided between the body 58 and presserfoot bar10 so that anynumber of needles which may be used in the sewing machinemay have free movement. a

It is understood that changes may be made in the various forms of myguard and in the manner and place of fastening the same to theresser-foot of a sewing machine or in forming the guard integrallytherewith without departing from the scope of the invention, therefore Ido not wish to be limited to the particular forms of guards hereindescribed and illustrated.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

In a sewing machine finger guard, the combination with the presser-footbar of a sewing machine, of a presser-foot having one end connected tothe bar, said presserfoot having at its free end a vertically disposedintegrally formed extension with-an aperture provided therethrough, anda transparent plate secured in the vertical extension across theaperture, whereby the fingers of a person may be protected while visionis unobstructed.
